and useful Improvements in Axle Journa1- Boxes for Outside-Wheel Locomotives, of which the following is a specification, refer ence being had therein to the accompanying drawin locomotives to the axles and track wheels upon which theyare mounted, and particularly to devices for mounting or sup orting the power-receiving axles in small ocomotives such as are used in mines. In some cases the conditions are such that the wheels can be located outside of the axle boxes. In others, they must belocated so that the journal parts of the axles will be situated outside of the wheels, as shown in my application Serial No. 853,770, filed July 28, 1914:. When the wheels are located outside of the journal boxes, I' have found that rovision must be made for taking the end t rust of the axles to the rigid parts of the truck frame,'and means for accomplishin this are herein illustrated and described.

f the drawings,

Figure 1 is a side elevation ofa locomotive provided with my improved journal boxes. I

Fig. 2 is a fragmentary horizontal sectional view taken along the line 2-2 of Fig. 3 is a fragmentary vertical sectional view taken along the line 33 of Fig. 1.

Fig. 4 is a fragmentary vertical sectional View taken along the line 4-4 of Fig. 3.

Referring to the drawings, 1 represents one of the outer side walls or lates forming one of the main elements of t e locomotive. This is shown as a single sheet of rolled metal, this being the construction preferred. This plate 1 is formed with apertures of suitable size or with wide slots or notches which extend upward from the bottom. These notches or apertures are adapted to receive the journal-boxes and the axles.

2, 2 are frame and spacin bars arranged vertically at the edges of'eac aperture and on the inside of the truck plate 1. To the guides for the axle box..

'body. 7, 7 are upwardly inner faces of these are secured the vertical plates 3, with their inneredges projecting somewhat beyond the bars 2' tov provide prevents displacement of the journal box, the latter being particularly liable to occur v in case the locomotive is derailed. V This invention relates to improved-devices for connecting the truck frames of cars or The journal box is indicated at 5. It is formed with an upper part 5,, a lower part '5 and connecting side parts; and in the latter there are formed grooves 4 which fit the guide edges' of the plates 3, the box bein allowed a vertical play relative to the truc opening sockets formed in the up er part 0 the box, and

- in these are seate the spring 8. 9 is a bar,

which is rigidly riveted to the truck plate 1, the horizontal part of the angle being near the planes of the upper edge of the aperture in the side wall and bearing downward upon the tops of these springs. 10 indicates the bearing piece or bushing, customarily made of brass, and arranged to rest and bear upon the journal part 11 of the axle 11. The weight of the truck part of the locomotive or cars bears downward through the parts at S), 8, 5 and 11 upon the wheel 12, and this in turn on the rails 13. It will be observed that the wheel 12 is secured to the ferred to.

An oil hole 5 is providedin each box 5,

this communicating with an oil groove in the bearing piece 10. Surplus oil can accumulateinthe chamber in the lower part of the box.

A socket is formed in the end of the axle 11 and into this there is tightly fitted a thrust element 15 which is preferably a hardened steel pin driven into an aperture formed in the shaft at its axis. An opposing thrust element 16-is provided and suitable means are provided for supporting this in position to cooperate with the element 15. The sup orting means shown is a longitudinal bar 1 which extends substantially from one end of the locomotive to the other past both of the axles. This can be supported in any desired way, and I have found that it can, in many cases, be conveniently supported, as shown, upon the boxes 18 which also serve as reservolrs for sand. The thrust member 16 is preferably a hardened steel plate tightly fitted into a seat in the bar. It can be fastened in any suitable way, as, for instance, by upsetting the end 16.

It will be observed that these" thrust taking parts 15 and 16 are so shaped, arranged and related that the endwise thrust of the axle is taken at points directly at or ad acent to its axis.

There are many sets of conditlons under which it is desirable to have the track wheels outside of the frame. One reason for this arrangement is the frequent'deslrability of keeping the overhaul width of the locomotive as small as possible. It will readily be seen that the placing of the necessarily large axle boxes outside of the wheels materially increases the total width of the locomotive. But with the construction shown the large axle boxes are on the inside and do not increase the width. For taking the end thrust of the axles I have provided a simple means which is outside of the wheels but which does not materially increase the width of the locomotive. This means comprises the bars 17 and the thrust plates 16 which engage the pins 15. By this construction I have not only provided a thrust means which does not-materially increase the width of the locomotive, but I have also provided one which is extremely simple in construction and is capable of being easily renewed in case of wear. I.

As stated, the parts 15 and 16 can be constructed of hardened steel and their position is such that no material can accumulate between their surfaces' In order to make renewal easily possible the parts are mounted in more or less exposed positions, but any grit which may fall on these parts will at once fall. from them. And if it is noticed at any time that excessive wear has occurred the bars 17 can be removed and the parts 15 and 16 taken out and replaced. It will be obvious that the bearing plate 16 can be easily removed from the bar by striking it at the end 16*. One way for accomplishing the removal of the pin 15 is to 'form a few turns of an external thread at the outer end of the pin prior to inserting it, and then, when the pin is to be withdrawn, rotating a suitable nut upon this threaded end which will quickly draw it loose.

I do not herein claim any of the subject matter for which claims appear in my earlier application No. 853770, filed July 28, 1914:; the claims herein relating more particularly to the form and arrangement of thrust elements when combined with wheels of the class of that herein; I preferring to claim in said earlier application the novel'features of construction which are common to both mechanisms.

What I claim is:

1. In a mechanism for mounting and holding a car axle, the combination of a journal box engaging with the journal part of the axle, a frame element carried by the journal box, a track wheel rigidly secured to the axle outside of the journal box, a thrust element removably connected to the. axle at its end, a second thrust element positioned outside of the said wheel, the said thrust elements being arranged to contact with each other at points which are proximate to the axis of the axle, and means supplemental to the axle and to the first said thrust element for holding the second said thrust element against movement longitudinally of the axis of the axle.

2. In a mechanism for mounting and holding a car axle, the combination of a journal box engaging with the journal part of the axle, a frame element carried by the journal box, a track wheel rigidly secured to the axle outside of the journal box, a thrust element removably'connected to the axle at its end, a second thrust element positioned outside of the said wheel, the said thrust elements being arranged to contact with each other at points which are proximate to the axis of the axle, and means supplemental to the axle and to the first said thrust element for connecting the second said thrust element rigidly to the said frame element.

3. In a mechanism for mounting and holding a car axle, the combination of a journal box engaging with the journal part of the axle, a frame element resiliently carried by the journal box and vertically movable relatively thereto, a track wheel rigidly secured to the axle outside of the journal box, a thrust element removably connected to the axle at its end, a second thrust element positioned outside of the said wheels, the said thrust elements being arranged to contact with each other at points which are proximate to the axis of the-axle, and means supplemental to the axle and to the first said thrust element for connecting the second said thrust element rigidly to the said frame element.

4. In a mechanism for mounting and holdin a car axle, the combination of a journa box engaging with the journal part of the axle, aframe element carried by the the free discharge of foreign material, and

means supplemental to the axle and to the first said thrust element for connecting the second" said thrust element rigidly to the said frame element.

5. The combination of a car frame, two axles extending transversely of the frame, track wheels rigidly secured to the axles outside of the frame, journal boxes engaging with the journal parts of the' axles inside of the wheels, longitudinal bars secured to the frame outside of the wheels adjacent the ends-of the axles and means serving to hold the axles against longitudinal movement.

with. the journal parts of the axles inside of the wheels, thrust elements connected to the axles at their ends, two longitudinal bars secured to the frame outside of'the wheels adjacent the ends of the axles, and'means serving to hold the axles againsttlongitudinal movement in either direction.

7. The combination of a car frame, two axles extending transversely of the frame, track wheels rigidly secured to the axles outside of the frame, journal boxes engaging with the journal parts of'the axles inside of thewheels, thrust elements connected to the axles at their ends, longitudinal bars outside of the wheels adjacent the ends of the axles, and second thrust elements carried by the bars and thereby held stationary longitudinally of the axle, said thrust elements being arranged to contact with, each other at points which are proximate to the axes of the axles.

In testimony whereof, I afiix mysignature, in presence of two witnesses.
